The invention relates to fences for jointers and other wood-workingmachines.

An object of the invention is to provide a work-guiding fence which isadjustably mounted at the front end of the work-receiving table of ajointer, or other woodworking machine, and below the top surface of thetable to thereby leave the table surface free from grooves or ways inwhich chips or sawdust may collect, or in which the work mayaccidentally engage to interfere with proper operation.

Another object of the invention is to provide fence-adjusting meanswhich are located at the front end of the table where they are easilyaccessible to the operator and do not interfere with the work.

A further object of the invention is to provide a fence which has apivotal axis extending substantially in the plane of the table, andwhich includes a depending portion at one end pivotally mounted on abracket ad'ustably secured to the front end portion 0 the table, suchpivotal mounting comprising a segmental ri on one member fitting in asegmental groove in the other co-operating member, and the fence havin aheel or lug which pivotally bears on the ta le surface adjacent thecutter-head of the machine.

A further object is to provide a fence mounting includlng a die-castbracket having a stop for quickly determining the position of the fenceat right-angles to the table, and also having an angular scale forfacilitating the angular adjustment of the fence.

A further object is to provide a fence which, with its supportingbracket, can be quickl and easily removed from the table, and whic canbe readily replaced on the table and be rapidly and accurately adjustedboth with respect to the cutter-head and with respect to the surface ofthe table.

A further object is to provide a rigid lightweight fence having anintegral longitudinally-extending tubular portion of substantiallytriangular cross-section;

A further object is to perfect details of construction of the fencemounting and to reduce the cost of manufacture in order to render thedevice suitable for small size ma- JOINTERS 1880. Serial No. 445,888.

Fig. 6 is a detail transverse sectional view pf the fence taken alongthe line 6-6 of Fig. 7 is a view similar to Fig. 6, but showing thefence in inclined position, and

Fig. 8 is a fragmentary detail View showing a modified form offencemounting.

In these drawings, the numeral 10 designates a jointer base frame havinga cutterhead 11 mounted in suitable bearings therein and driven in anysuitable manner. A front table 12 and a. rear table 13 are slidablymounted on inclined ways 14 formed on the base frame 10, so as to beindependently raised or lowered with res eat to the knives of thecutter-head, as usua The adjusting means for the table includes a pairof adj usting nuts 15, each of which is threaded on a respective screw16 secured to the base frame.

The front table 12 is provided at its front end with a guide channel 17which extends transversely along the under side of the table in parallelrelation to the axis of the cutterhead. The opposite side portions ofthe channel 17 are formed with rooves 17 of rectan lar cross-sectionwhic slidably receive t erein the opposite flanges 18 of a diecast metalbracket 19, portions of which depend from the channel 17 and extendforwardly of the front end of the table 12. A clamping screw 20, havinga slidably mounted handle 21 in its head portion, is threaded angularlyinto the bracket 19 to engage an abutment 22 formed along the upper wallof V the channel 17, to thereby urge the bracket downwardly andforwardly into firm engagement with the grooves 1 By this adjustment theforward flange 18 of the die-cast bracket is brou ht to bear against thelower and side face 0? the forward roove 17, and the vertical forwardface 23 o the bracket 19 is brou ht into a plane at right-angles to theupper ace of the jointer table 12.

An arcuate segmental rib 24 projects integrally from the forward face ofthe die-cast bracket 19, and is concentric with a horizontal axis whichis normal to the forward face of the bracket 19 and which liessubstantially in the plane of the upper surface of the jointer table, orin some instances slightly above the table surface. A plate 25 bearsagainst the vertical surface 23 of the bracket 19 and is provided withan arcuate segmental groove 26 within which slidably fits the segmentalrib 24 on the bracket, to thereby define for the plate an axis ofrotation lying substantially in the plane of the upper surface of thejointer table.

A shouldered clamping screw 27 having'a slidably mounted handle 28 inits head portion, is threaded into the bracket 19 and extends through anarcuate slot 29 formed in the plate 25. The shouldered head portion ofthe screw 27 engages a washer 29 which receives the screw therethroughand which bears against the plate 25 to clam the plate in angularlyadjusted position. X lug 30 is formed integrally on the die-cast bracket19 and has a stop-screw 31 threaded therein for engagement with a lug 32formed on the plate 25, to thereby limit the angular displacement of theplate in one direction. A look not 31' holds the screw 31 in ad'ustedposition. An angular scale 33 is molded on the die-cast bracket 19 andco-operates with an index pointer 34 secured to the plate 25, to therebyfacil tate the angular adjustment of the plate. The index pointer 34 isof angular shape and has one end portion rotatably fitting within a lbore formed in the edge portion of the plate 25. The pointer can therebybe swung into pro or registration with the scale 33, and is hel inposition b a set screw 34.

A fence 35 is xedly secured to the upper portions of the plate 25 bymeans of screws 36, and presents a flat work-enga ing face 37 whlch isdisposed at right-ang es to the uppersurface of the table 12 when thelug 32 on the fence plate engages the stop-screw 31. The fence 35 isprovided with integral re-enforcin walls 38 which form therewith a rigidtu ular structure ta ring toward the ree end of the fence an presentinga substantially triangular crossesection. At t point adjacent thecutter-head 11, a rounded heel or lug 39 is formed on the lower edge ofthe fence to pivotally engage the upper surface of the jointer table 12and thereby prevent springing of the fence by a downward pressure,especially in the inclined positions of the fence. A recess 40is formedin the lower edge of the fence to provide clearance for the cutter-head.

In the modified form of fence mounting shown in Fig. 8, the jointertable 112 is provided in its front end portion with atransversely-extending channel 117 opening laterally to receive aflanged die-cast bracket 119 which is urged forwardly and downwardlyagainst the recessed walls of the channel by means of a clamping screw120. The plate 25 carrying the fence 35 is fitted on the bracket 119 ina manner heretofore described, and is clamped thereto by a screw 27.This form of fence mounting is generally similar to that first describedexcept for the disposition of the channel 117 which opens laterallyinstead of downwardly.

The assembl comprising the fence 35, fence plate 25, and liracket 19, isof 'unitary charactor, and is capable of being shifted transversely ofthe table, or removed from the table, after loosening the clampin screw20. During such shift or removal, t e flanged portions 18 of the bracket19 slide along the grooves or ways 17 of the channel 17, which is openat its opposite ends. When the fence assembly is to be replaced on thetable, the bracket 19 is slid into the open-ended channel 17 a selecteddistance and the screw 20 is then tightened to clamp the assembly firmlyin place. When the screw 27 is tightened, the fence plate 25 is clampedfirmly against the forward vertical face of the bracket 19, whereuponthe fence 35 extends longitudinally of the table 12 and at right-anglesto the axis of the cutter-head. The abutment of the lug 32 with the stoscrew 31 serves to place the plane of the ence at right-angles to theupper surface of the table 12. In this manner, the more commonly used 90adjustment can be readily obtained. When the angular position of thefence is to be ad- 'usted, the screw 27 is loosened and the fence plate25 rotated to a selected position as indicated by the position of thepointer 34 with respect to the scale 33, whereupon the tightenin of theclamping screw 27 will secure the once firmly in its adjusted position.

The clamping screw 27 not only clamps the fence assembly a ainstmovement, but also insures a disposition of the fence at rightangles tothe axis of the cutter-head, so that rabbeting, tenoning, and moldingoperations can be accurately performed.
